List Standing Intents

list_standing_intents

Read-onlyIdempotent

Use this when the user asks which data center watches are registered on their key: webhook watches, plus your capacity requirements (kind "capacity", intent_id cap_...). Read-only. Returns each intent_id, kind, watch params, webhook_url and enabled state; capacity items also carry status, confirmed, expires_at, last_alert_at and matching_now. Use it to find the intent_id for delete_standing_intent, or to confirm a register landed. Requires a key (or an OAuth connection for capacity items). Answers "what am I currently watching". Do NOT use to create a watch (register_standing_intent) or for one-shot reads (get_news / list_transactions).

A4.6/5.0

Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already cover read-only, idempotent, non-destructive, closed-world behavior. The description adds value beyond that: it discloses the key requirement and the OAuth-connection requirement specific to capacity items, plus what each returned record contains. It stops short of rate-limit or pagination behavior, so 4 rather than 5.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Front-loaded with the primary trigger, then return shape, then auth, then exclusions in a logical order. Slightly long with some overlap between the opening trigger and the closing 'what am I currently watching' paraphrase, but every sentence carries actionable content.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With an output schema present, the description need not enumerate return values, yet it summarizes them usefully; annotations cover the safety profile and there are no parameters to document. An agent has everything needed to select and invoke this correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The tool takes zero parameters, so the baseline is 4. The description correctly adds no parameter guidance because there is none to give, and instead explains what the empty-argument call returns.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ('list standing intents / data center watches registered on their key') and enumerates the two kinds it covers, including the 'cap_...' capacity prefix. It explicitly names what it is not (register_standing_intent, get_news, list_transactions), so an agent can separate it from siblings without opening schemas.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Gives concrete triggers ('when the user asks which data center watches are registered', 'to find the intent_id for delete_standing_intent', 'to confirm a register landed') and an explicit exclusion list of alternative tools for creation and one-shot reads. Nothing is left to inference.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
